What type of energy is stored In capacitor?

What type of energy is stored in inductor?

The plates of a parallel plate capacitor have an area (20 cm^2) each are separated by a distance of 2.5 mm. The capacitor is charged by connecting it to a 400V supply. How much electrostatic energy is stored in the capacitor?

Draw a graph showing the variation of charge stored in a capacitor with its potential. How will you calculate the energy stored in the capacitor using the above grah?

When we double the separation between two plates by keeping V constant, what happens to total energy stored in the capacitor?

Assertion : When a dielectric slab of dielectric constant K is introduced between the plates after disconnecting the battery, energy stored in the capacitor decreases. Reason : Potential difference between two plates decrease by a factor K ad charge remains the same, so energy decreases.

Derive an expression for energy stored in a capacitor,
